In case you can't tell, I am seriously pondering all this "Spirit" stuff. So, I did a search, including; of the Spirit, through the Spirit, with the Spirit, and some others I can't remember right now and guess where I hit the jackpot? In the Spirit. A lot of cool stuff seemed to happen when someone was "in the Spirit". In the beginning of his Revelation John said, "On the Lord's Day I was in the Spirit, and I heard behind me a loud voice like a trumpet... " John was whisked all around his Revelation "in the Spirit".
That makes me think of a different translation of Gal 5:25 Since we live by the Spirit, let us keep in step with the Spirit. It almost makes me wonder ~ if the Spirit inside of us, is lined up with whatever God is doing through His Spirit on earth, do we get to experience real God stuff? Does that make any sense? Kind of like the whole "Experiencing God" thing. If we are focused on Jesus and are seeking Him and trying to keep in step with what He is doing, we will be running strong, in the Spirit.
If we are living a little bit for God and mostly for ourselves, is that what keeps us from experiencing His power? Because we are not "keeping in step with Him". I think He will still save us, if we ask Him to, but will we miss out on doing His work here on this earth?
